Specification of lLetters Patent.

Application led September 29, 1913. Serial No. 793,285.

To all whom t may concern.'

Be it lknown that I, J ULiUs BRENZINGER, a citizen of the United States, residing at Mount Vernon, in the county of lVestchester and State of New York, have invented certain new and useful `Improvements in CanTHeading Machines, of which the following is a specification.

rIhis invention relates to 'machines for securing the tops and bottoms to the body portions of sheet metal containers, such as what are known as tin cans, by the double seaniing process. The present invention contemplates further improvements, particularly by way of simplification, in connection with a can heading machine such as shown and described by me in my earlier Patent, No. 1,167,346, granted January 4,

1916, and further contemplates additional .improvements in means for automatically feeding the assembled can parts to the seaming mechanism, such as shown and described by me in another earlier Patent No.

seaming mechanism as tofi'etain' each can body and its top or cover in their properly assembled condition, so that these parts will be relatively positioned for the. seaming op# eration. Furthermore, it will be apparent that while thelmovement of the containers must beintermittent, in order to provide periods of rest during each of which a seaming operation is performed, such movement must be steady and the actuating mechanism such that the containers will not be abruptly.

started and stopped or otherwise jarred in transit, so that 'the loose tops or bottoms maynot be dislodged while being advanced to and 'positioned in the sea-ming mechamsm.-

Still vfurthermorerit will be' apparentthat the operations of the feeding and seaining mechanism must be necessari-ly interrelated in order that the seammg operation be performed while the container which has been positioned is at rest. `Still furthermore, when the container to be sealed is brought tov proper position, it must be gripped by the seaming mechanism in such manner that thelv `top or bottom will not be dislodged by initial engagement with theseamingmechanism therewith.

In attempting to provide a machine having the qualities and free from the objections suggested above, I have also kept in mind the simplification of the seaming mech-- anism with particular reference to the -a'ctuating means therefor, whereby I may iiicrease the capacity of the machine through al construction which will permit of ahigher speed of relative movement between -the can to be. sealed and the sneaming .rollers,"iiring ing the seaming rollers more rapidly from non-effective to effective positions aiiif'tyvitlidrawing the same more rapidly from effec` tive positions after the seaming operation-f this, in connection with positively timedl relative movements `of parts and a 'wholly automatic seaming operation. -I might add that the present invention also contemplates a machine in which operation of the feeding mechanism may be quickly checked, vas vit should b when a container to loe-sealed is improperly positioned or the head thereof hasbecome dislodged to the point of: not only preventing the production of the desired seam but possibly to the extent of clogging the machine and breaking a part or parts thereof, without the necessity o machine and thus having to overcome the inertia of these parts both in stopping and starting with consequent loss of time..

My invention will be more readily underf stood by. reference to the accompanying drawings, forming a part of this specification, in which,

Fig. 8 is detail sectional view of the clutch mechanism shown in Fig. 6, as hereinafter more fully described, and y Fig. 9 is an enlarged section taken substantially on the line 9 9 of Fig. .2.

eferring now numeral l1 designates the supporting frame of the machine which is preferably provided with a heavy base to give the same rigidity and stabilit-y. In 'the lower portion of this frame is journalcd the shaft 12 upon which is mounted the driving pulley 13 designed to have the usual belt connection with any suitable source of power. In the upper portion ofthe frame 1l is journaled the shaft 14 upon which are mounted the pulleys 15 and 1G whereby said shaft 14 may be driven at variable speeds from the pulleys 17 on the shaft 12 by means of the belt 13.

In forwardly projecting arms land 20 of the frame 11 is mounted the hollow rod 21, carrying at its lower end the chuck 22 which, in the common and well-known manner, is designed to enter the central depression in a can top and support the overlapping flanges of the top and body portion of 4the can for the scaming operation.,

.lournaled in these forwardly projecting arms 19 and 2() is the shaft 23, rotated from the shaft 1,4 by means of the intermeshed bevel gears 2l and Surrounding the rod 26 to which is secured a gear 27 in mesh with a gear 28 on the shaft 23, whereby said sleeve 2G is rotated on said rod` said sleeve being supported by said gear 27 which rests upon the shoulder formed by the thrust-bearing 3G. The sleeve 26 carries at its lower extremity a cylindrical eccentric head 2S, journaled upon which 'is a collar 29 provided at its lower end with a iiange or disk portion 30, the peripheral edge of which is tip-turned and said upturned portion interiorly screw-threaded for the reception of the annular washer 31.

A collar 3l has a bearing on the sleeve 26 and surrounds the collar 29. This collar is supported for independent rotation upon the shoulder formed b v the eccentric head 2S, and isprovided at its lower end with a flange 35, the edge of which enters the groove formed between the washer 31 and the disk 30, thus rotatively supporting said collar 29 through the disk portion 30 thereof. Mounted on the upper face of the disk portion 30 of the collar 29 is a swivel-block 3T (Fig. 9) slidable in a radially disposed slot in the liange 35. wherefore it will be seen that while the collar 3l is supported by the eccentric head 2S, these members rotate independently of each other, and while to the drawings in detail,

Ytance within the end of the collar 29 with its disk portion 30 is co'nnected with the collar 34 and its flange 35 through the swivel-block 37 in the slot 38, whereby the former. is rotated by and with the latter, these members have a certain freedom of-bodily movement laterally with respect to each other. Y,

The gears 27 and 28 being of the same size, the sleeve 26 with its eccentric-head 28 will be rotated at the same velocity as the shaft 23. At the lower end of the shaft 23 is provided a gear 39 in mesh with a gear 40 on the collar 34. The gear 39 is of slightly greater diameter than the gear 40, whereby said collar 34 will be rotated at slightly greater velocity than the shaft 23, and, therefore, at a slightly greater velocity than the sleeve 26 with its eccentric head 28. Therefore, as the sleeve 26 and the collar 3l are rotated, the former will travel at a slightly less velocity than' the latter, whereby the relative lpositions of the eccentric head 2S'and the collar 34 will be constantly varied to change the position ofthe disk 3l) relative to the rod 21 which carries the chuck 22. This relative movement, controlled by the swivel-block 37 in the slot 38, is fully shown and described by me in my earlier Patent No. 1,167,346, aforesaid, and for the purposes of this descriptionV it will suiiice to state that as the eccentric head 28 and the collar 29 are rotated at slightlydifferent velocities, the seaming rollers 33, suitably mounted on one side of the tool-carrying ring which is detachably secured to the underside of the disk portion 30 and the collar 29, will be successively brought into and out of w'orlcengagtng positions with respect to the chuck 22. The configuration of the working edge of each of the rollers 33 and that of the chuck 22 are too well known to require detailed description here, and the same is true with respect to the effect of the cooperative operation of rollers and chuck.

Mounted on the shaft 14 is the worm 44, in mesh with a gear 45 loose upon a bushing 'TLG on the shaft 47, this shaft having hearings in the branches of an arm 48 projecting upwardly from the main frame of the machine. The bushing 46 with the thrust-collar 49 are fixed to the shaft 47 `by means of the pin 50, one end of the shaft -zl7'being bored out to receive the end of the rod 51, and this hollow end of the shaft 47 being provided with longitudinal slots (Fig. 8) through which passes a pin or key 53 carried by the rod 51. This pin or key 53 is also secured at its ends to the collar 54 of the disk 55 which is loose upon the shaft 47. It will be seen, therefore, that the rod 51 may be reciprocated for a limited disthe shaft'47 and thereby reciprocate the disk 55, these members, however, necessarily rotatilw in uni son. To the face of the disk 55 1s secured the semi-annular member 56, an opposite and corresponding semi-annular member 57 being secured to the contiguous face of the gear 45. The gear 45, loose upon the shaft 47, is continuously rotated, and it will be apparent that as therod 51 is reciprocated loi'igitudinally within the bore at the end of the shaft 47, reciprocating therewith the disk 55 and its half-ring 56, the disk 55 will be forced in thedirection of said gear 45, and lat one pointin each revolution of said gear the half-ring 56 will clear the half-ring 57 andbe engaged by the latter to rotate the shaft 51 and therewith the shaft 47.

I have described above a preferred form of clutch mechanism for rotating the gear 58 on the shaft` 47 from the constantly rotating shaft 14. This particular construction of clutch mechanism, however, is not essential to my invention, as it will be apparent that the shaft 47 may be driven by the shaft 14 through the interposition of any one of various formsl of connections which are capable of disconnection when desired in many different ways. Nevertheless, attention is directed to the fact that any clutch mechanism employed should engage the shaft 47 and rotate the gear 58 at the same point in the rotation of the gear 45, for reasons which will be hereinafter made clear. This is preferably accomplished by me inl the manner described, through the employ,- ment of the half rings 56 and 57, one mounted on the constantly rotating element 'and the other on the element to be rotated.

The gear 58 is in mesh with the `gear 59 on i the shaft 60 which has bearing in the-arm 48 of the frame of the machine. This shaft 60 carriesfthe beveled gear 61 in meshwith the gear 62'on the shaft 63. Mounted on the shaft 63is the 'disk 64 having a cam-groove 65 (see dotted lines in Fig. 6) within lwhich rides a roller at the end of the arm 66 of a bell-crank leverpivoted at `67 to the frame of the machine. Aconnecting rod 68 con nects the end of the arm 66 with the arm 69 of a similar bell-crank lever pivoted at 70, the other arms 71 and 72 of said levers having pivotal connection with the lugs 73 and 74 of a frame which contains ahorizontal run-way '7 6 fora roller 77. It will be apparent that upon rotation of the shaft 63, the cam-groove 65 in the'disk 54 will operate to os'cil-late the arms 66 and 69, thereby alternately raising 'and lowering the frame 75, this frame being vertically reciprocatedonce foreach revolution of the canwdisk 64 on the Shaft 63.

^ Suitably mounted in the frame of the machine are the horizontaland parallel guide-v rods 7 8 and 7 9, slidable and rotatable upon which are the sleeves 84 and 85, respectii'fely.V Secured to. these sleeves are the bars or levers and 81, respectively, the meeting end s of whichv are preferably of-set or half out 85, respectively,

' the medium of said bars.' y

Rigidly secured to these sleeves 84 and are the opposite and correspending frames 86 and 87, the frame 86 including the collars 87 and 88 on the sleeve 84 and the downwardly projecting arms 89 and 9.0. Similarly, the frame 87 includesthe dewnvL-ardly projecting arms the lower ends of thearms 89 and 90. is secured a casting 95, and at the lower ends of the arms 93 and 94 is mounted the casting 96. lfhese castings 95 and 96 are of similar configuration,` each being provided with preferably three recesses 97, these recesses being circular 'in shape and arranged in pairs, whereby a circular can body may be engaged between opposite' recesses of each pair.

. It willA be apparent that ashthe frame 75 "collars 91 and 92 on the sleeve 85 and the 93 and 94. At

is raised and lowered, thereby rocking the arms 80 and 81 1n opposite directions, the sleeves 84 and 85 will be correspondingly rocked, operating through -`the frames 86 and 87 to reciprocate the members 95 and 96 horizontally, these members thus having the eifect of jaws which close and open to enage and release can bodies interposed thereL etween.

On the shaft 63 is also mounted the diskwheel 98 to which is pivoted the connecting rod 99, at the other end of which are provided the rollers 100 adapted to travel in horizontal runways 101. This connecting rod is designed to reciprocate the carriage which includes the frames 95 and 96, and in order to provide for a feature of adjustability, I interpose a substantially triangularshaped member 10Q, having pivotal connection with the connecting rod 99 and to which is pivoted the connecting rod 103, the other end of whichis pivotedl to the arm 104 of a bell-crank lever pivoted at 105. Themennber-102 is provided with a vertical slot 105 through which .projects a stud or pin (not shown) on the rod 99, said stud or pin being `threaded for the reception of the clamping' nut 106, whereby the' relativeA position of the member 10Q may be rotatively varied to adjustably vary the relative position of the rods'99 and'103, whereby'the starting and stopping positions of the' plate or carriage -107 may be varied. The lever 104 is pivoted in lugs projecting upwardly from a plate 107, this-plate being secured to and moving with the sleeves 84 and 85. Projecting upwardly from this plate are the' arms 108 and 109, carrying at their tops the cross bar 110, between which and the plate 107 is interposed the arm 111 which comprises the other arm of the bell-crank lever referred to. This arm 111, therefore, has a certain freedom of movement between the cross-bar 110 and the plate 107, whereby upon initial movement of the disk-wheel 98 and the connecting rod'99, upon rotation of the shaft 63, a certain interval of time will elapse prior to movement of said plate 197 under action of the connecting rod 103. VThis interval of time is to provide for the action of the disk-wheel 64 with its cam groove 65, which operates, just prior to movement of said carriage in one direction, to lower the frame 75 and close the can-engaging members 95 and 96 and engage the can bodies which have been properly positioned therebetween.- Immediately followingr the engagement of these bodies, the disk wheel 98 will operate through the connecting rods and the lever 101, the arm 111 of which has now impinged against the plate 107, to carry said plate 107 in what may be termed a forward direction, carrying therewith the can bodies which have been engaged thereby and positioning the foremost of said bodies in the seaming mechanism.

Similarly, when the disk wheel 98 has turned through a half revolution, the arm 111 of the bell crank lever will be raised to contact with the plate 110 before the connecting rod 103 has the effect of operating to return the plate 107 to its initial position and therewith the members 95 and 96. During this interval of time, the disk wheel 64 with its cam-groove will have operated to raise the frame and thereby withdraw the members and 96 from engagement with the can bodies to clear the saine and permit of the return of said members to proper position for rengagement with the next succeeding can-bodies for repetition of the above-described operation.

The duration of these time intervals may be adjustaliily varied by means of the adjusting screw 111 in the upper face of the arm 111, the extent of projection of which may be varied to slightlyincrease or decrease thc length of the vertical stroke of said arm aud thus correspondingly vary duration of each period of rest prior to reciprocation ofthe plate or carriage 107.

lSuitably supported at one end upon the frame of the machine, and at the other end in any desired manner, I provide a r unway for the can bodies which comprise Ireferably two plates 112 and 113, separated to provide a space 111- therebetween for purposes which will be hereinafter set forth. I have shown secured to theseplates side guide strips 115 and 116, respectively, and

the provision of a top bar 117 so positioned as to retain the-superposed-tops of the can bodies in place in transit to the seaming mechanism. In mesh with the gear 62 on the shaft 63, driven by the gear 61 on the shaft 60, is the bevel gear 11,7 ofthe shaft 118, which carries the bevel gear 119 in mesh with a corresponding gear 120 on the vertical shaft 121. This shaft 121 is provided with the bevel gear in mesh with a corresponding gear 122 on a horizontal shaft 123 which is provided with a sprocket wheel 124' over which passes a chain 125, the upper leg of which runs in the space 114 between the plates 112 and 113. This chain 125 is provided with a series of lugs located at such distance from each other as to engage a series of can bodies and advance the same along the runway provided by the plates 112 and 113 and advance the forwardy can body to such position as to be engaged between the rearward recesses 97 in the members 95 and 96, substantially as shown'and 4 described in detail in my earlier Patent No.

1,167,345, aforesaidV It has already been explained how the members 95 and 96 serve to grip this can body and advance the same one step, then release the same and return for the engagement of the next succeeding can body. At the same time the last-mentioned can body is being engaged, the one last engaged and advanced is again engaged by the middle recesses of the members 95 and 96, and so on,

the foremost can body at each operation being positioned upon a preferably circular platform 126 on a vertical rod 127 and which is located directly underneath the chuck 22.

Projecting from the bearing collar 128 on the shaft 60, is an arm 129 to which is pivoted a bell-crank lever having one arm 130 provided with a roller operating in a cam groove 131 the face 132 of the gear 58 on the shaft 47. The other arm 133 of said bell-crank lever has pivotal connection at its end with one en d of the rod 131 the other end of which is pivoted to the lever 135 fulcrunied at 136 in the frameof the machine. This lever 135 has connection through the llnks 136 with a vertically v reciprocating carriage 137 which is adapted to raise and lower the rod 127 and therewith the platform 126, shown and described in another earlier Patent, No. 1,167,318, granted to me January 4, 1916, wherein, however, the platform was raised by hand instead of automatically as in the present invention.

The cam groove 131 is of such configuration that the rod 131 is lowered to raise the platform 126 just prior to effective coperation between `the seaming rollers and the chuck After this operation, the platform 26 is automatically lowered, and the seaming operation having been elfectcd,

substantially as It is well known to those skilled in thisV art that. the, compression of the flanges from which the seam isformed against the chuck 22, frequently results in the frictionalV engagement of the can which preventsothe same from being lowered by gravity with'the platform `126. For the purpose of disengaging the can from the chuck after the seeming operation, I provide a plunger rod 141, reciprocable for a` limited distance within the hollow' rod 21 and provided at its end with the pusher head 142. At the upper end of this rod is provided a cross bar 143 coiinectedby links 144 to the ends of arms on. short shaft 146. This shaft is rocked by means of the lever arm 147, the free end of which is provided with a roller and which is raised and lowered by means of the cam 148 on the face of the gear 58. As the shaft 146 is rocked, it will be apparent that the. rod 141 will be raisedand lowered, and this opeiation isso timed by the cam 148 that said rod is depressed simultaneously with depression of the platform 126. This construction and operation is substantially the same as described by mein other earlier patents, more particularly Patent No. 1,167 ,346, aforesaid.l

Under normal conditions of operation', the gear is secured through the clutch describeti,to the shaft 47, whereby rotation of said "snaft 47 is continuous and the@ cans are automatically fed at proper intervals to the platform 126 in the manner described. In the event that a top or cover should be come dislodged, or should a can body be' vimproperly positioned, under which circumstances continued operation of the feeding mechanism would tend to clog the machine operating through the arm 151 and the rod engaging devices prior to movements of the and-possibly result in a breakage of lsome` part or paits thereof, I desire to provide for a stoppage of the feeding mechanism without stopping the operation of the other moving elements of the'machine, as hereinbefore suggested. I therefore provide an A arm 151 pivoted to the shaft '63 which has suitable pivotal connection at its other endwith the rod 51,' this connection being shown-between the two collars 152 and 153 on said rod. To this arm 151 is pivoted the hand-lever 154, projecting to an accessible point in front of the machine, this lever 51to separate the disk 55 and its half ring 56 from the gear 45 a nd the half ring .57, whereby the gear 45 will run loose upon the shaft 47'and operation of the feeding mechanism will be thereby stopped.

In order to insure operation of the'can reciprocating carriage-i,A I may provide a brake-bar 156 adapted to be frictionally engaged to a greater or less degree between the Cross-bars 157 and 158, mounted upon the pins or posts 159 and 160 projecting downwardly from the plate 107. Compression springs 161 act against the bar 157 to provide this frictional engagement with the bar 156, and it will be apparent that by thus yieldingly retarding movement of the carriage, operation'of the members or 'jaws 95 and 96 is insured prior to reciprocation of said carriage:

To further insure the retention of the loose can heads in proper positions on the can bodies during transit to the seeming mechanism, I provide pins 162 projecting upwardly from the members 95 and 96 and so positioned as to Contact with the edges of the can cover when the can body is en gaged by the members or jaws 95 and 96- these covers, prior to the seeming operation, projecting beyond the side walls of the can bodies.

construction, dependable' in operation and 'capable of operating at a high speed without great danger of breaking a part or parts thereof through improper positioning of the work or dislodginent of one oi both of the assembled parts to be joined together.

Many modifications of minor details oi my improved can heading machine will doubtless readily suggest themselves to those skilled in the art to which it appertains, and I therefore do not desire to limit my invention to the specific construction herein shown and described.
